摘要
Dianions derived from chiral imidazolines 1a-c, undergo selective one-electron oxidation reactions in the presence of TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxy) and form metallated radical species. Depending on the reaction conditions the radical intermediate is trapped stereoselectively by TEMPO, or undergoes a dimerization reaction. (C) 1999 Elsevier Science Ltd. All rights reserved.
